To'aZZ whom t may 001106701:

Be it known that I, lJOHN M. Lown, a citizen vof the United States, residing at Butler, in the county of Dekalb and State of Indiana, have invented a knew and useful `Wifndmill Regulator, of which the following is a specification. I

This invention aims to provide a-vnovel and ketiicient means whereby the operation of a wind mill may be controlled automaticall Ill-iris with-in the province of the disclosure to improve generally and to enhance the utility of devices of that type to which .the invention appertans. e e

I .do not bind myself to the specific details of A.construction depicted and described, for, although the drawings show a preferred embodiment of the invention, al mechanic, working within the scope of what is claimed, and exercising such skill .as might be expected of him, may make changes, without departing from the spirit of the invention, or jeopardizing the utility of the device.

In the accompanying .drawings F igure 1 shows, in elevation, a device constructed in accordance with the invention, the tank appearing in section; Figure 2 isan elevation showing a portion of a. wind mill post, the device forming the subject matter of this invention beingmountedthereon, parts being omitted, yand parts appearing insection; .Figure 3 is a vertical section onthe line of Figure 2,; Figure 4; is va cross sect-ion on the line 4-1 of Figure 3; Figure 5 is .a- `cross section lon the 'line 5 5 of Figure 3, Figure 6 `is la sectional .detail illustrating a modification. v A

The numeral 1 designates, generally, the tower of a wind mill, .embodying an inwardvly inclined post 2, a Icross brace 3, and other V,common parts, the pump rod lbeing marked by `the numeral e and being operated from ,the wind wheel (not shown), in the usual manner, through ythe instrumentality of a gearing (likewise not sho-wn), whereby the wlilid wheel may be stopped and started at w' l.

The post -2 Vcarries a support, denoted gen-A erally by .the numeral 5, the support; being a composite structure, and including side `plates 6 and 7, having flanges 8 yadapted to .engage the post 2, .as shown in Figure 4. the

side'plates being connected, andbeing -held upon the post 2,` by an upper securing ele.-

.ment `or .bolt 9 and a lower securing .element 10, which connect theplates adjacent gto the post. Onits inner side, the plate 6 is.` suppliedwith a pocket, 11, having the function of a paw'l-stop, as v hereinafter explained,

the pockctjand't'he rplate 6 carryingan upper socket `12a-nd a lowersocket '111.5 .One endv Q, of a pivot piny 15 is ysecured inthe socket 14 the corresponding endof a fulcrum pin 16 being secured in the socket ,1"2,y the pins '15 and 16 being slidable in the plate 7 ,the con-l struction v"being such that theplatef' may be adjustedtoward and -awayfrom the plate- 6,. so as to accommodate `tower posts 2 of different widths.l The plate 7 may be sup.-

plie'd with a boss 17, wherein thek fulcrum pin 16 is received, a. set screw 18 being threaded into the boss and enga-ging thepin 16, the pin, therefore,fcooperatingwith the securing elements. 9 ,and 10, to aid in holding the support 5 .on the post 2. y l

The numeral 19' marks a 1everwhich is mounted to swingvertically on .the ulcrum pin 16, in engagement with the socket '12,- ,a Cotter pin `2O or .the like being carried by the pin 16,v 'to hold the lever 19 in place, as shown in Figures 2 and 4l. At its inner end,

'being pivoted thereon at. 23. "The outeren'd- `the lever 19 yhas a fork 21, ,ang-actuating l i vont the actuatingpawl is weighted as at 211,

so as to throwfthe opposite .end of the pawl .'inwardly, the'last speciiied-end'of the'pawl being provided with a lateral linger 25,'re-

ceived within the pocket 11 of the :side plate,A

.6, the inner wallof the pocket cooperating with the nger to serve as astopvfo'r the pawl,

A back stop- .pawl 261s mounted to 'swing on' ,thepivot pin 15 and is held engagement with the socket 14 by 4means of a Cotter pin'27-carried bythe `pivotpin 115,* It will b e ,Observed that the llever'19 the actuating paw'l 22 and the'back `stop pawl 26 cannot move horizontally with respect "to thefside :plate 6, the supporti-.5 being-f expanded? or contracted, to fit different sizesfof posts, by shifting the side plate with respect to vthe side plate 6 and with respect to the pawl 26, the pau/'122 and the lever 19.. V'The 4jbacjk stop p awl 26 is weighted ,at its upper end, as at,

28, so aste throw the-'lower end of the pawl inwardly,the,inwardmovement of the pawl i being limited,l however, by a lateral fingerl l" i 29 011 .the .pawL this fnger being adapted t9 cooperate with alug- 30 which'projects inwardly from the side plate 6.

'lille lever 19 includes l`an ,extension 3,1, i

whereon a rider 32 is mounted for adjustment, longitudinally of the lever, the rider being held in adjusted positions by a set screw 33, which, being threaded into the rider, bears on the extension 3l of the lever. The lower' ends of links 35 are pivoted at 34 to the rider 32, the upper ends of the links being united by a clamping bolt 36. The numeral 37 marks a connecting member, whichmay be a wire, the lower end of the connecting member having a loop 200 engaged about the bolt 36 and clamped between the upper ends of the links 35, the construction being such that the length of the connection 37 may be adjusted. The upper end of the connecting member 37 is attached to a bracket 38, mounted on the pump rod 4, it being` noted, incidentally, at this point, that the pump rod serves to impart vertical swinging movement to the lever 3l-,19.

A radius arm 39 is located between the I` side plates 6 and 7 of the support 5, and is mounted to swing on the lower securing element l0 which unites the plates. An L shapedlatch 40 is provided, one end of the latch being pivoted at 4l to the upper end of the radius arm, the other end of the latch extending outwardly across the upper edge of the side plate 6, and being adapted to cooperate with shoulders 201 and 42 formed therein. The numeral 43 marks a trip lever,

placed externally of the plate 6 and fulcrumed intermediate its ends thereon as at 44, swinging movement of the lever being limited by stops 45 and 145 on'the plate.

, headed detent 72 is slidable in the plate element being rove through a Ablock 49 arm 39, intermediate the ends thereof, and

mounted pivotally on the cross brace 3 of the tower l.' From the block 49, the flexible element 48 extends downwardly across a guide sheave 50, journaled on a standard 5l carried by a tank A. float 53 is located in the tank 52, the flexible element being attached to the float. The wind mill operates the rod 4; the pump of which the rod 4 is a part delivers water to the tank 52 through a pipe 54; and, as shown in Figure l, the float 53 issupported on the liquid in the tank.

A. guide 55 is pivoted at 56 to the radius in the guide, a rack bar 57 is mounted for reciprocation, an offset extension 58 being secured at 59 to the upper end of the rack bar.

rilhe teeth of the rack bar are markedby the numeral '60, and, above the teeth, there is a smooth surface 61, located on the Vrack bar and on the extension 58 thereof.

A slide 62 reciprocates on the post 2. The slide 62 comprises a body or block 63,

having an outer groove 64 in which the upf per end of the extension 58 of the rack bar 57 is received, the inner surface of the block or body 63 being provided with a groove 65, disposed at right angles to the groove 64 and receiving a pair of overlapped meinbers 66 and 67 having flanges 68 engaged loosely around the post 2. A securing element, such as a screw 69, passes through the upper end of the yextension 58 of the rack bar 57 and through the'block 63, the securing element being mounted in the member 66, and the member 67 having a slot 76 through which the securing element 69 passes, the members 66 and 67 being bound lirmlyupon the block 63 by the securing element. t is to be noted that the member 66 is fixed relative to the block 63, whereas the member 67 may be adjusted with respect thereto, to accommodate posts 2 of different widths. rFhe lever 19-31 and the pawls 22 and 26, it will be recalled, are fixed against lateral movement with respect to the plate 6, the adjustment in the width ofthe support 5 being brought about by shifting the plate 7 inwardly oroutwardly. Since the member 66 is fixed with respect to the block 63, the member 67 being adjustable, the rack bar 57 is always held in I alinement with the pawls 22 and 26, so as to coact therewith, even though the support 5 and 'the slide 62 may have been increased or diminished in width, to fit posts of difcause the slide can tilt on the post, the rack .A bar 57 is permitted to have a slight swinging movement in the direc-tion of the arrows A and B in Figure 3, to the end that the rack bar may be brought into and out of engagement with the pawls 22 and 26.

To the upper Yend of the extension 58 ofthe rack bar 57, a connecting element 71 is secured, this connecting element extending upwardly, and being connected operatively,

in the usual way, with the gearingof the wind mill, (not shown).

Suppose that the tank 52 is filled to the desired level. Then, the trip lever 43, responding to the weight 46 rests on the stop 145 and is out of engagement with the latch 40, the latch being engaged with the shoulder 42, the radius arm being swung into the position shown in Figure` 3, the rack bar 57 being swung away from the post 2, the teeth 60 of the rack bar being engaged with the back stop pawl 26 andA with the actuating pawl 22, and the detent 72 having been sure pipe, wherewith a casing 74 communi' Cates, the casing containing a yieldable diaphragm 75; responsive to pressure in' the pipe 7 3. A plunger 76 slides in the casing 74 and includes a foot 77 resting -on the diaphragm 75. A lever 78 is supported intermediate its ends on the plunger 7G; and is ulcrumed at 79 on the casing, t-he lever carrying a weight 80; held inadjusted po-` sitions by a set screw 8l, a flexible element 82 being connected to the lever' 78, and corresponding in function to the fievible'ele-v ment 48 ot' Figure` l.
